| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Merely being able to play an LP side without skipping or obvious distortion is not itself proof of good tracking.An oscilloscope has been indispensable in our mastering operation. Test equipment can be quite handy for moving from anecdote to more ... | |
| Is this possible? I was under the impression ( maybe mistakenly) that one needed at least some kind of phono stage due to the RIAA requirement to utilize a SUT. You need a phono section with RIAA eq to use any phono cartridge using a magnetic operating principle, ... | |
| Hi end tube preamps, it’s all about functionality!! Bet it will sound better than any "high end" preamp.The value of the bet being how much you paid for this... The 6BL7 is a nice tube, but with only one the circuit possibilities are limited. But in the right situation it should sound quite nice. | |
| Any high end preamps out there where tubes off while HT in use? Any high end preamps out there where tubes off while HT in use?Why would anyone want this?? You'd have to wait an hour or so for the preamp to sound right if you wanted to use the 2-channel. | |
| Audio Research Amplifier Balanced Input Question ralph can this be done just with passive components?Yes- the Jensen transformers I mentioned. This is the part needed:https://www.jensen-transformers.com/product/pi-2xx/There are several versions- the one needed has XLR and RCA connections. | |
| Receiver recently repaired - Now producing fuzzy distortion in higher frequencies?? I suspect that the bias diodes used to give thermal feedback from the heatsinks are shorted. This will cause the amp to sound exactly as described. It causes the amp to have extreme crossover distortion. I would take it back to the service shop an... | |
| Class D Technology @noble100 OK- I just wanted to be clear on what was meant by 'switching distortion' since that's not an engineering term at all!Artifacts from dead time show up as harmonic and intermodulation distortions, so a class D amplifier can easily be comp... | |
| Hi end tube preamps, it’s all about functionality!! Hi end tube preamps, it’s all about functionality!!This statement is false; this thread is based on a false assumption. Maybe we can disabuse that. In high end audio, the goal is getting the music to sound real. Many preamps have that as a goal. C... | |
| Audio Research Amplifier Balanced Input Question The Reference 110 is very unhappy with a single-ended source! Essentially its input circuit has a very poor Common Mode Rejection Ratio (CMRR); another way of putting that is that it will have high distortion and low gain if operated by a single-e... | |
| Resistive loading The lower the impedance of the load the less highs you will hear. But its important to keep in mind that its not so much for the cartridge as it is for the preamp. The cartridge and phono cable form a tuned radio frequency circuit which can be tri... | |
| What is the best audiophile speaker for a tiny square room? How does class A fit into the sound quality equation for AS amps? Some people say for tubes, class A doesn't make that much difference- the way it does in SS amps. What do you think?Class A in a push-pull amp is nice because it helps reduce dist... | |
| What is the best audiophile speaker for a tiny square room? You're going to be hard pressed to beat the Soundlabs. Are you sure you shouldn't be looking for cool-running non-class D amps instead?I’ll have to object to your blanket assertion. Class D goes swell with MY ESL’s. Better than the last three AB’... | |
| So you have a great hi end stereo preamp, but you can’t funnel any sound from your ht system thru this magical box.Uh, sure you can. With ****any**** preamp. | |
| Which tubes are the best? JJs are available from CE Distribution cedist.com | |
| Class D Technology @timlub What is the 'switching distortion' to which you refer? Obviously No Switching distortion. |
